What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
I followed the engine start checklist, but a first start attempt was unsuccessful. I had engaged the starter for approximately 7 seconds in the first attempt, therefore I waited about 40 seconds before retrying per the starter limitations. Before I could initiate a second start attempt, I saw pilots in front of me waving and yelling smoke. I immediately turned the fuel selector to off, removed the keys, turned the master off and exited the airplane. I saw smoke on the front of the plane, ran over to the fire extinguisher station and told bystanders to call 911. I sprayed the fire extinguisher on the front of the cowling. I then returned to the cockpit to verify that master and fuel was off and exited when visible smoke reappeared. After 1-2 minutes of smoke, flames became visible just prior to the fire department arriving. Once the fire was extinguished, I gave my information to the onsite fire commander.
As the FAA filed it
I FOLLOWED THE ENGINE START CHECKLIST, BUT A FIRST START ATTEMPT WAS UNSUCCESSFUL. I HAD ENGAGED THE STARTER FOR APPROXIMATELY 7 SECONDS IN THE FIRST ATTEMPT, THEREFORE I WAITED ABOUT 40 SECONDS BEFORE RETRYING PER THE STARTER LIMITATIONS. BEFORE I COULD INITIATE A SECOND START ATTEMPT, I SAW PILOTS IN FRONT OF ME WAVING AND YELLING SMOKE. I IMMEDIATELY TURNED THE FUEL SELECTOR TO OFF, REMOVED THE KEYS, TURNED THE MASTER OFF AND EXITED THE AIRPLANE. I SAW SMOKE ON THE FRONT OF THE PLANE, RAN OVER TO THE FIRE EXTINGUISHER STATION AND TOLD BYSTANDERS TO CALL 911. I SPRAYED THE FIRE EXTINGUISHER ON THE FRONT OF THE COWLING. I THEN RETURNED TO THE COCKPIT TO VERIFY THAT MASTER AND FUEL WAS OFF AND EXITED WHEN VISIBLE SMOKE REAPPEARED. AFTER 1-2 MINUTES OF SMOKE, FLAMES BECAME VISIBLE JUST PRIOR TO THE FIRE DEPARTMENT ARRIVING. ONCE THE FIRE WAS EXTINGUISHED, I GAVE MY INFORMATION TO THE ONSITE FIRE COMMANDER.
